- ings, making part oft-his specification.

Our invention relates to the means for tripping and releasing orstopping and starting the binding mechanism, and for regulating the sizeof the bundles, and to means for locking or holding thebinding-mechanism gearing against back action or throw during the timeit is thrown out of action, and will be understood from the followingdescription, reference being had to the accompanying drawings, in

which Figure 1 is a front elevation of so much of a harvesting-machineas is necessary to show our improvements. Fig. 2 is a plan view of a pertion of the same. Fig. 3 is a front elevation of the tripping mechanismdetached, showing also other parts in connection with which saidtripping devices act. Fig. 4 comprises two detail views of the clutchconnected with the main binder-gear shaft, and Fig. 5 represents ahorizontal section through the binder-gear standard and a portion of thegear-wheel on the knotteractuating shaft.

The machine represented in the drawings is of that class in which thegrain is bound on an inclined elevatingtable located at the inner sideof the platformcarrier and receiving the grain directly therefrom, andthe devices hereinafter described are arranged with especial referencethereto; but it will be apparent that some of these devices may be usedupon other forms of machine, if,,desired; also, that the machine, in itsorganization or construction and arrangement of parts as awhole, issimilar to others now in use, and need not therefore be described indetail further than is necessary to an understanding of ourimprovements. t

A represents the forward sill of the platform-frame; B, a combinedgearbloek and chair rigidly secured to the inner end of sill A adjacentto the main drivewheel, and B a second chair of less height than chai-rB, the

Serial No. 133,498. (No model.)

chairs B and B forming supports for the forward ends of two longitudinalbinder-frame sills, O and O, which are connected by suitable inclinedtransverse sills or bars 0, form ing a support for the inclinedbinder-table. (Not shown.)

To the forward inclined transverse bar, G or to the chair B, is securedthe binder-gear standard D, having tubular arms D D which projectrearwardl y, one over and the other under the binder-tablc, and formsupports for the needle and knotter-actuating Shafts and bindermechanism in a manner well understood.

E is a longitudinal bar, supported above the path of the grain to thebinding devices by straps and braces e 6', connecting it with the uppertubular arm, D, of the binder-gear standard, said bar E forming asupport for one end of the knotter-shield E, also for the upperbearing-bracket, E of the butter-shaft, and in practice for the pendentbearing'brackets of the shaft actuating the pickers or gatherers, asshown in Letters-Patent No. 27 6,448, granted to me April 24, 1883.

F represents the main binder-gear shaft,

which is mounted in suitable bearings in the gear-block B andbinder-frame, and to which motion is imparted from the main drive-wheelof the machine in any usual or preferred manner.

Motion is imparted from the shaft F to the various operative mechanismsof the machine, and among these to the binding mechanism, as follows:

a represents a pinion loose on the shaft F near its forward end, andadapted to be engaged therewith by means of a dog, a, pivoted to theforward face of the pinion, and adapted, when not rocked inward towardshaft F, by means hereinafter described, to engage a spur, b, on across-head, b, rigidly secured to the shaft F, directly in front of thepinion a, for causing the latter to be rotated with the shaft F in amanner well known.

and rotating with the shaft F, the pinion a serves, through intermediatepinions,a and a, to drive a spur-gear, a", fast on the knotteractuatingshaft, 0, and thencethrough suitable crank-wrist, crank, andconnecting-rod e to the vibrating needle-shaft 0.

\Vhen coupled to IOO To the forward inclined transverse bar,(l ,of theb1nder-frame,or to other suitable support, s secured a curved or angularbracket, d, havlng an eye or perforation in its forward end, forming abearing for a sliding stop or dog, 9, projecting downward from theangleor elbowof a bel1-crank-shaped arm or bar, G, the upright arm or leg ofwhich is pivoted to a crank, It, on the forward end of a rock-shaft, H,mounted 111 suitable bearing-brackets attached to the bar E. The arm ,9of the angular bar G proects outwardly, and at its outer end rests upona cam, 0 on the shaft 0 immediately in rear of the crank-arm c" on theforward end of said shaft, for a purpose which will be explained.

The rear end of shaft H has a crank-arm, h, formed upon it, whichprojects outwardly over the knottershield E, and has the upper end ofapendent link, i, adjustably connected with it, said link: passing downthrough a slot in the shield E, and having its lower end pivoted to arod, I, which is pivoted at one end to the knottershield E near the barE, and at its outer or free end overhangs the grain accumulating on thebinder-table to forma bundle.

The rod I lies inclining downward and outward over the binder-table, andas the grain accumulates and becomes packed by any usual or preferredmeans for that purpose it gradually crowds the rod or arm I upward, andthe latter, acting through the link i and arm h, rocks the shaft H,lifting the angular bar G and withdrawing the pendent spur or dog 9outof the path of the end or nose a of the dog a, freeing the latter andallowing it to be forced outward by its spring a to engage thecross-head b, and thus coupling the pinion to its shaft for actuatingthe binding mechanism. As the arm 0 of the needle-shaft "is rockedupward, the cam c on said shaft acts on the arm 9 of thebell-crank-shaped arm G, and serves to hold the latter, with the spur 9,up out of the path of the end or nose 0!, of the dog a until the shaft 0is returned to its former position of rest, when the cam allows the barG to descend, again interposing the spur g in the path of the end ornose a on the dog a, forcing said dog inward out of engagement with thecross-head 12, allowing the pinion a and binding mechanism to remain atrest until the action of the grain on the arm I above described isrepeated for again setting the binding mechanism in motion. The heightof the free end of arin'I may be adjusted as desired by means of aseries of perforations in the upper end of its supporting-link t,through any one of which perforations it may be connected by a pin orother suitable fastening with the arm h of the rock-shaft H. The shaft His provided with an upright arm, h, having a series of perforations atdifferent distances from the shaft H, through any one of which a spiralspring, 3', may be connected with said arm, said spring extendingoutward and having its outer end connected with a bar, J, passingoutward through a guiding-loop, j, so cured to the upper face of thegear-standard sleeve D, The bar J has a notched or ratchetcd lower face,adapting it to engage at any point in its length with a tooth formed inthe lower wall or side of the loop j, and is provided at its outer endwith a loop or handle, j", Within convenient reach of the driver in hisseat, who, by adjusting said rod J, and with it the tension of thespring j, can regulate at will the resistance to the upward movement ofthe arm I, and thereby the size of the bundle and the degree ofcompression of the grain required to lift the arm I for tripping orsetting in motion the binding mechanism.

For holding the gearing of the binding mechanism and preventing any backaction after the binding mechanism has been released from theactuatingshaft F, the gear-wheel a on the knotter-actuating shaft isprovided on its rear face with a cam-shaped projection, is, inclined onits forward face relatively to the direction of movement of the wheel,and having an abrupt rear face adapting it to act upon and crowdbackward a roller, 1, journaled in the forward end of a sliding pin, L,movingin suitable ways or perforations in the gear-standard D. A spiralspring, Z, surrounding the shank of the pin L between a shoulder formedthereon and the rear bearing for said pin, serves to crowd the pinforward, with the roller resting and rolling in contact with the camuntil the latter has passed the roller. when thelatter is immediatelythrust forward behind said cam just as the wheel a*completes itsrevolution and is thrown out of action, and thereby serves toeffectually hold the latter and the binder-mechanism gearing against anyback action.

Having now described our invention, we

claim as new- ,1. In a grain-binder, a rock-shaft mounted upon thebinder frame and a toothed or notched bar connected adj ustably by aspring to a crank-arm on the rocloshaft and engaging a spur on saidframe, in combination with a tilting arm in contact with the accumulatedgrain and connected to the rock-shaft,whereby the resistance of thetilting arm may bevaried by the adjustment of the toothedbar,substantially as described.

2. In a grain-binder, a rock-shaft mounted upon the binderframe and apivoted lever also mounted upon said frame in contact with theaccumulated mass of grain, in combination with a bell-crank-shaped armconnected to an arm of the rock-shaft, a pendent .link connecting thepivoted lever with the rockshaft, and a dog mounted upon the mainbinder-gear shaft and engaged by the lower end of the bell-crank-shapedarm,substantiall y as and for the purpose described.

3. Aroek-shaft and a pivoted lever mounted upon the binder-frame, saidlever being in contact with the accumulated grain, a gear-wheel mountedupon the main binder-gear shaft and carrying a swinging dog, and a camupon the needle-shaft,in combination with a bell-crankshaped armconnected to a crank-arm upon said rock-shaft, and having an armextending in operative engagement with the dog on the main binder-gearshaft and engaging the said swinging dog atits lower end, substantiallyas 4. The combination, with the gear-wheel mounted upon the mainbinder'gear shaft and carrying the swinging dog, and the cross-head uponsaid shaft, of the bell-crank-shaped arm connected to a erank'arm upon arock-shaft mounted upon the binder-frame and engaging the dog at itslower end, and the toothed or serrated bar connected to a crank-arm ofthe said rock-shaft and engaging with the upper arm of the binder-frame,substantially as and for the purpose set forth.

5. The sliding dog for stopping and starting the binder mechanism, incombination with a cam on the binder-arm shaft for holding said dog upafter it has been raised to trip the binder mechanism and until theoperative movement of said mechanism is completed, substantially asdescribed.

6. The angular bar provided with the sliding dog for stopping andstarting the binder mechanism, in combination with the rockshaft andpendent arm or lever adapted to be acted upon by the grain, and the camon the shaft for raising and upholding said dog, substantially asdescribed.

9. The rock-shaft and means, substantially as described, connectedtherewith for tripping the binder mechanism, in combination with thecranlcarm and spring, and the ratchetbar for adjusting the tension ofsaid spring and regulating the resistance to the tripping of the bindermechanism and the size of the bundles, substantially as described.
